Based on the George Romero 1979 gore classic, this remake takes place as the United States is overrun (after a plague) by millions of corpses who walk the earth as cannibalistic zombies. A small group of survivors, including a nurse (Sarah Polley) and a police officer (Ving Rhames), try to find shelter within a massive shopping mall. But the zombies have a kind of sense memory and start arriving -- in droves -- for a shopping spree.
